Factors affecting the amount of corroded iron converted into adherent rust in steels submitted to immersion tests

Quantitative approach in iron oxides and oxyhydroxides by vibrational analysis

“…The quantification of iron oxides by infrared spectroscopy is not common, although a good number of qualitative studies are found in literature [4,6,7]. Recently, proposals to use infrared [9] and Raman spectroscopy [13] in quantitative studies on iron oxides have been reported.…”

“…The precise determination of these relative amounts of each phase presented in rust is one important task for researchers from the corrosion workers [6,7].…”

A Micro-Raman Spectroscopic Study of Marine Atmospheric Corrosion of Carbon Steel: The Effect of Akaganeite

“…8 Lepidocrocite is believed to form in the initial stages of atmospheric corrosion [9][10][11] and transform to goethite in certain conditions. Akaganeite is formed only in the presence of salinity 7 and was widely found in marine environments 12,13 and in chloride-rich solutions [14][15][16] and soils. [17][18][19][20] Raman spectroscopy, as a powerful non-destructive spectroscopic technique, has been successfully used for the identification of pure iron oxides [21][22][23][24] and steel corrosion products.…”

“…[17][18][19][20] Raman spectroscopy, as a powerful non-destructive spectroscopic technique, has been successfully used for the identification of pure iron oxides [21][22][23][24] and steel corrosion products. [8][9][10]12,[14][15][16][17][18][19][20][24][25][26][27][28][29][30] Its ability to distinguish between the various phases of iron oxides and oxyhydroxides, which are normally found in atmospheric corrosion products, is extremely helpful in the identification of corrosion products.…”

Corrosion behavior of ultra-high strength steel 300M in different simulated marine environments

“…Salt spraying test is commonly used to simulate marine atmospheric corrosion environment. García [7] and Pérez [8][9][10] estimated the service life of weathering and carbon steels in simulated marine atmospheric environment by total immersion corrosion method, and found that porous rust on the steels in Cl-containing solution included γ-FeOOH, the most abundant, and α-FeOOH, Fe 3 O 4 , and adherent rust on CS and WS was Fe 3 O 4 , and γ-Fe 2 O 3 , respectively. Sun [11,12] and Yu [13][14][15] investigated corrosion behavior of 300M and AF1410 in simulated marine atmospheric environment by salt spraying test, and found that the outer rust on the steels was mainly composed of γ-FeOOH.…”
